I was trying to remove the egr valve, j guess theyre sensor hoses? Well i tried removing them by hand and they just snapped like twigs. So im sure i need to replace it before i can even start my car up. The hoses all attatch from the egr valve and the fuel rail pressure sensor and all connect between, idk the engine or intake or something.

Im going to have to take a lyft to autozone and wanted forum help so i can call them about the hoses i need first, but idk what the part i need is called

 

Welcome to the site..
Very common for the plastic vacuum lines to snap with age and heat. Sections can be repaired with rubber vacuum hose, and there are vacuum push on/in fittings to connect the rubber hose to the rubber connectors where the plastic has broken off at their bases..

 

Thx, i bought a bunch of stuff from autozone, made some new connections. I think the car sounds like more high pitched fast clicking than usual. Im about to drive to autozone right now.

Do you have advice for unscrewing the egr valve? The big nut wont budge and i dont want to break it. Im gonna ask a few people on monday. My thought is to spray rust penetrant on it, but i dont know which car parts is ok to spray this or that chemicle around it
